I was experiencing some screen tearing on video with Flash Player 9, and thought perhaps giving Flash Player 10 a try would help. It didnâ€™t help much, but hereâ€™s how you can install Flash Player 10 yourself using nspluginwrapper on 64-bit Ubuntu. I did this on Hardy Heron, but similar steps will probably apply to previous or new distributions.

This guide is written for Ubuntu Linux but can easily be converted to any other GNU/Linux distro

Firstly, you need to remove any existing installations of Flash using nspluginwrapper.

Close Firefox.

From the terminal type nspluginwrapper -l. This shows you all current plugins using nspluginwrapper. For example:

Remove any other traces of Flash and nspluginwrapper. Note if youâ€™re using nspluginwrapper for something else, do NOT remove itâ€™s folder or package, instead look through the folder and see if thereâ€™s anything remaining that is related to Flash. Otherwise you can run these commands:

Extract it, change into the directory it extracted to (something like install_flash_player_10_linux)

Make sure youâ€™ve closed Firefox again, then copy libflashplayer.so to the Mozilla plugins folder like so:

sudo cp libflashplayer.so /usr/lib/mozilla/plugins/

Now you need to download the required 32-bit libraries and manually install them.

Open up a terminal, make a new directory somewhere and change into it, then download the required 32-bit library packages using the following commands (note, these versions may be old if you read this in the future):

Note that for me, sound just worked straight out of the box. Iâ€™m using the bog standard PulseAudio set up with (as far as I can remember) no extra tweaks to get sound working. If you have any issues, or this guide doesnâ€™t work (Iâ€™m remembering the steps as best as I can to write this) then leave a comment. If itâ€™s been useful to you, leave a comment too!

Edit:

Today, Ubuntu announced the first Intrepid Ibex beta. I gave my Linux workstation an upgrade immediately to give it a try. I received a suggestion that you can also use an Intrepid Ibex package to install Flash Player 10 on Hardy Heron, which is a great suggestion and a lot easier than my method.

Now I have Intrepid Ibex, and that package is available, installing Flash Player 10 on 64-bit Ubuntu is a snap:

apt-get install flashplugin-nonfree

Yup, thatâ€™s it. Reload Firefox and youâ€™re done! I must say though, it seems a little less stable than it was in Hardy Heron, but then Intrepid Ibex is still in beta.
